Esse (ens) dupliciter dicitur. What does Aquinas mean by this distinction? T. Veres, who first indicated the fundamental importance of this distinction in the metaphysical thought of Aquinas, interpreted it as eine fundamentale ontologische Dichotomie. On the other hand, H.Weidemann regarded it as two semantically different uses of the verb “be. ” In this paper, I intend to argue against both Veres and Weidemann and attempt a more sophisticated interpretation.The view presented by Veres faces two serious difficulties, which are necessarily caused by his ontological interpretation. Weidemann's semantic explanation of Aquinas' dichotomy of being in accordance with Fregean trichotomy fails because the Fregean distinction of the 'is' of existence, of predication, and of identity doesn't seem to be consistently applicable to Aquinas.I interpret Aquinas' distinction between esse ut actus essendi and esse ut verum from a semantic viewpoint as being the distinction between two aspects of significare, i.e. res significata and significatum. Significare means not only to refer to things (res significata), but also to make conceptions understood (significatum) by expressing them. Thus esse (ens) dupliciter dicitur means, on the one hand, that esse refers to reality, and, on the other, that esse, combining a predicate with a subject as a copula, expresses an affirmative proposition as known to mind and asserts its truth.
